I have ACCEPT_KEYWORDS="~ppc-macos" in my make.conf, however, I should not even need the "~" to emeger some version of portage, eh? Has ppc-macos support dropped from Gentoo entirely, or am I reading too much into this?_________________|

You are right! WTF!?! I fall asleep for a couple months and Gentoo Max OS X is no more on the ppc platform. Damn! I never get those memos._________________|

That's not entirely true...there are packages that are supported on that platform (see http://packages.gentoo.org/archs/ppc-macos/), but portage isn't one of them. Seems kind of silly, really...but I don't know when that happened, or how (I use x86 and and64, myself).
